SFS Plano-Convex Lens

Overview

Premium UV fused silica lenses designed for demanding laser and imaging applications.

VenusLab Fused Silica (SFS) Plano-Convex Lenses are manufactured from high-purity UV Fused Silica (JGS1) or Corning 7980 substrates.

These lenses offer superior transmission from the ultraviolet (UV) to the near-infrared (NIR) range. Featuring a surface quality of 40-20 and exceptional thermal stability, they are the ideal solution for high-power laser collimation, UV focusing, and applications requiring high resistance to thermal shock and scratches.
